Latest News! 3 August 2000: Update on the catalog. The ROSAT consortium released on the 25 of May 2000 "The Second ROSAT source Catalog of pointing observations with the PSPC (ROSPSPC / 2RXP)" (ROSAT News No. 72). The WGACAT final version, released on 1 May 2000 was cross-correlated with the previous version of ROSPSPC (known also as ROSATSRC) released first in November 1994. On the 2 May 2000 (ROSAT News No.71) the ROSAT consortium also released an update of the ROSAT HRI catalog containing 30 % more sources compared to the previous version released in August 1999 (ROSAT News No. 69). We re-run the cross-correlation process using these new catalogs and also the updated version of the VERON (VERON2000) catalog. All the parameters derived as result of the cross-correlation were updated and/or recalculate. The WGACAT now contains these new cross-correlations results (1 August 2000). 20 May 2000: Release of the final version of WGACAT. The catalog is available from the HEASARC on-line service and includes more than 88000 sources.
